Though the review states that exFat is not supported it does, in fact,support exFat. I formated a hard drive as exFAT, plugged it into the USB port via an OTG cable and it worked just fine. I also formated aSD card as exFAT and put into the Excite's SD card reader and it worked as well,

Android 4.0 supports ExtFAT across the board, regardless of brand or model. FAT32 is also good to go, but NTFS is iffy due to licensing requirements. The manufacturer must license an NTFS driver such as Paragon's to support NTFS.
